"Cameron Diaz is still at the top of the list, and Drew Barrymore is there," Radcliffe stated on the radio show "Capital Breakfast."
In a 2014 interview with Us Weekly, he said of her and Drew Barrymore, "I had images of her and Drew Barrymore posted to my bedroom wall."
While playing a game in which he was entrusted with answering three juicy questions openly, the "Lost City" star was compelled to disclose his celebrity obsessions with "Capital Breakfast."
A Radcliffe superfan would be punished with something unpleasant if he refused to answer or dodged a question.
Aside from celebrity obsessions, Radcliffe has been in a long-term relationship with Erin Darke for over ten years.
Radcliffe played Allen Ginsberg and Darke played Gwendolyn in the 2013 film "Kill Your Darlings," in which the two met.
Darke most recently starred in the third season of Radcliffe's TBS sitcom "Miracle Workers."
In March, Radcliffe told People, "We absolutely appreciate [working together], but it's not something we want to do all the time." "Obviously, we met on set, so working with her on 'Miracle Workers' last year was extremely memorable and felt wonderful."
